I applied for the internship process in the Visa Research crypto team through the portal and reached out to one of the researchers. I spoke with two researchers who were my potential mentors in two different interviews. I prepared a presentation of 10mins which briefly summarizes my works and publications. They asked few questions during that presentation and we spoke about the implications of my results and future works.
They also described me about the different ongoing projects in the group and the research interests of other researchers.
Fortunately their projects aligned with my research interests and I got the offer. I was notified about the result in less than a month and I accepted it.
